What is the rest of the problem? I would answer this if you had more info on it. :D
Answer: You find the area by multiplying all the sides up. It is similar because a triangle needs to be times by bxh and so does a rectangle. They're different because they are different shapes
Step-by-step explanation:
1. I suppose the ODE is supposed to be
Solving for 
gives
which is undefined when 
. The interval of validity depends on what your initial value is. In this case, it's 
, so the largest interval on which a solution can exist is 
.
2. Separating the variables gives
Integrate both sides. On the left, we have
where we substituted 
- or 
- and 
- or 
.
On the right, we have
So
I'll leave the solution in this form for now to make solving for 
easier. Given that 
, we get
and so our solution is
